如何在预定时间内使用倒数计时器？

我的代码

<html>

<head>
    <script type='text/javascript' src='http://code.jquery.com/jquery-1.10.2.min.js'></script>
    <script type='text/javascript'>
        $(document).ready(function() {
            var seconds = 6;
            var minutes = 1;

            function calculate() {
                setTimeout(calculate, 1000);
                $('#showDate').html(' expires after ' + minutes + ' minutes ' + seconds + ' seconds ');
                seconds--;
                if (seconds < 0) {
                    seconds = 59;
                    minutes--;
                    if (minutes < 0) {
                        minutes = 0;
                        seconds = 0;
                    }
                }
            }
            calculate();
        });
    </script>
</head>

<body>
    <div id='showDate'></div>
</body>

</html>

以上代码仅适用于分钟和秒。如何添加小时和天？

    <script type='text/javascript'>
        $(document).ready(function() {
            var days = 4;
            var hours = 0;
            var minutes = 0;
            var seconds = 6;

            function calculate() {
                setTimeout(calculate, 1000);
                $('#showDate').html(' expires after ' + days + ' days ' + hours + ' hours ' + minutes + ' minutes ' + seconds + ' seconds ');
                seconds--;
                if (seconds < 0) {
                    seconds = 59;
                    minutes--;
                    if (minutes < 0) {
                        hours--;
                        minutes = 59;
                        if (hours < 0) {
                            days--;
                            hours = 23;
                            if (days < 0) {
                                days = 0;
                                hours = 0;
                                minutes = 0;
                                seconds = 0;
                            }
                        }
                    }
                }
